DETAILED DESCRIPTION

Modern collaborative workspaces (conference rooms, huddle spaces, classrooms, etc.) are plagued by ineffective, messy, and confusing video conferencing, power, and connectivity solutions. Although many technology providers offer integrated solutions for video conferencing that include full NV connectivity to a projector, TV, or display, they all suffer from an inability to connect the devices of multiple conference participants at the same time and further fail to provide simple functionality to swap presenters easily.

The present disclosure relates to a conferencing device that solves these (and other) issues. The conferencing device of the present disclosure may leverage, among other possible choices, Universal Serial Bus (USB) compliant hardware and cabling in order to facilitate communication with an external host device (e.g., a device that is presently using, or may in the future use, the conferencing device to present a presentation to a group). A USB cable between a conferencing device of the present disclosure and an external host device may provide data transfer between the devices, power transfer between the devices, or both. While all types of USB are contemplated as possibilities for performing either or both of these power transfer and data transfer functions, it is noted that given the rise of USB Type-C (USB-C) devices, providing device charging and presentation data connectivity simultaneously via a USB-C cable is becoming increasingly relevant.

FIG. 1 illustrates an embodiment of a conferencing device 100 which includes a processor 102 and a memory 104. The processor 102 may be in electrical communication with the memory 104 such that information may be stored and retrieved by the processor 102 to and from the memory 104. The processor 102 may be in electrical control and communication with any of the other elements 104-124 of the conferencing device 100, enabling it to send data to and/or receive data from each respective element 104-124.

The conferencing device 100 may include a USB hub 106. The USB hub 106 may be, e.g., a USB-C hub, another type of USB hub, or a hub of hybrid USB type. The USB hub 106 may further include USB ports 106A-F. The USB ports 106A-F may each respectively be USB-C ports or ports of another USB type. Each of the USB ports 106A-F may include a physical USB interface that allows an external host device, also referenced herein as a portable electronic device, to be placed in electrical communication with a USB port 106A-F to communicate with the USB hub 106. For example, the USB port 106A-F may communicate with an external host device/portable electronic device using a USB cable that is attached to the respective USB ports 106A-F via the physical USB interface. In alternative embodiments, the USB interface may itself comprise a USB cable (which is not removable from the USB hub), which may then electrically communicate with an external host device.

The USB hub 106 may allow for data transmission to and from any external host device in electrical communication with the USB port 106A-F and the processor 102. Among other things, the USB hub 106 may receive video data and/or control signals provided by an external host device and further transport the control signals and/or video data to the processor 102. The USB hub 106 may also allow for data transmission between any external host device in communication with a USB port 106A-F and any other device in communication with another USB port 106A-F.

The conferencing device 100 further includes a power supply 108. The power supply 108 may provide power to any or all of the other elements 102-124 of the conferencing device 100. In one embodiment, the power supply 108 may be in electrical communication with the USB hub 106 in order to provide the USB hub 106 with power that the USB hub 106 may then pass along to any external host device in communication with any of the USB ports 106A-F. The USB hub 106 may provide power to one or more external host devices at the same time that the USB hub 106 provides the data communication features described herein to those one or more external host devices.

The conferencing device 100 further includes a video out module 110 that includes one or more video out ports 110A, 110B and video out wireless interface 110C. The video out module 110 may be capable of receiving video data from the processor 102 and displaying it on one or more of the video out ports 110A, 110B and video out wireless interface 110C. The video data may be provided to the processor 102 by one or more external host devices in communication with the USB hub 106.

The video out ports 110A, 110B may be of different types. For example, it may be that video out port 110A is of a High Definition Media Interface (HDMI) type while video out port 110B is of a DisplayPort type. Other types of video out port include Digital Video Interface (DVI), Video Graphics Array (VGA), an RCA video out port, or any other port configured to transport video data provided by the processor 102. One or more video out ports 110A, 110B may also be capable of transporting audio data over an interface that also handles audio data (e.g., via an HDMI interface). In FIG. 1 , the video out module 110 is illustrated as having two video out ports 110A, 110B and a video out wireless interface 110C. However, one of skill in the art will appreciate that other embodiments may include one, three, four, or any other number of video out ports or wireless interfaces.

The conferencing device 100 may further include an expansion port 112. The expansion port 112 may be configured such that a second conferencing device may be connected to the expansion port 112 of the conferencing device 100. As further described below, when the conferencing device 100 is connected to a second conferencing device, the two conferencing devices may act together as a single logical conferencing device that can support more connected external host devices than can be supported by one conferencing device alone. The expansion port 112 may include a USB interface for connection to a second conferencing device. The expansion port 112 may be a separate port from the USB hub 106, as illustrated in FIG. 1 . Alternatively, any of the USB ports 106A-F on the USB hub 106 may be able to act as an expansion port when connected to either the expansion port or an analogous USB hub port of a second conferencing device.

The conferencing device 100 may further include a network interface 114, which may include either or both of a physical interface 114A (e.g., an Ethernet interface) and/or a wireless interface 114B (e.g., an 802.11 wireless transceiver) to communicate with other devices on a computer network. A network connection established with the network interface 114 may allow the conferencing device 100 to connect to and coordinate with other devices, including remote conferencing devices. In this way, the conferencing device 100 may be able to pass data to remote conferencing devices that are not directly connected to the conferencing device 100. This data may include video data, audio data, and/or control signals from one or more of the external host devices that are connected to the USB hub 106 of the conferencing device 100. In this way, one or more remote conferencing devices that are not physically attached to the conferencing device 100 may be able to participate in the same conference as the conferencing device 100. In some embodiments, an external host device may communicate with the conferencing device 100 over the network interface 114 instead of over a connection to the USB hub 106, even in cases when the external host device is not remote to the conferencing device 100.

The conferencing device 100 may use speakers to reproduce audio associated with the presentation (e.g., the voice of a presenter or other participant in the video conference). The conferencing device 100 may use one or more of a built-in speaker 116, a speaker attached to an audio out port 118, and/or a speaker connected to a Bluetooth interface 124 for this purpose.

The conferencing device 100 may also use microphones to capture audio associated with the presentation (e.g., the voice of a presenter or other participant in the video conference). The conferencing device 100 may use one or more of a built-in microphone 120, a microphone attached to an audio in port 122, and/or a microphone attached to the Bluetooth interface 124 for this purpose.

FIG. 2 illustrates a conferencing system 200 of a conferencing device in a conference room setting, according to an embodiment. The system 200 includes a conferencing device 202, which may be similar to the conferencing device 100 of FIG. 1 , in use with a conference table 204. In the embodiment of FIG. 2 , the conferencing device 202 is shown in dotted lines to represent that the unit has been integrated into (or installed underneath) the conference table 204 rather than simply placed on top of the conference table 204. Each of the USB cables 206A-F may be coupled to a USB hub of the conferencing device 202. The USB cables 206A-F may each respectively be a USB-C cable, or alternatively may be a cable of another USB type. Hybrid cables (e.g., where one end is, e.g., USB-C and a second end is, e.g., USB-A) are also contemplated, which may allow for functionality between a port of a USB hub of the conferencing device 202 that is of one type of USB and an external host device with a USB interface of a different type of USB.

Each USB cable 206A-F may have a connector to couple to a corresponding device to allow power/data communication. In FIG. 2 , connectors 207E-F are illustrated and, although connectors corresponding to cables 206A-D are not shown, connectors for cables 206A-D would also be included to enable interfacing with corresponding devices. The connectors 207E-F may include any structure and adapters well known in the art to enable an interface with devices for power/data communication.

A power cable 208 may be in electrical communication with a power supply of the conferencing device 202. The system 200 may include a video cable 210 in electrical communication with a video out module of the conferencing device 202. Similar to the conferencing device 202, the portions of these cables that are adjacent to the surface of the conference table 204 have been shown in dotted lines to represent that those portions of each of these cables are integrated into (or installed underneath) the conference table 204 rather than simply placed on top of the conference table 204. The integration (or underneath installation) of the conferencing device 202 and/or the USB cables 206A-D may reduce clutter on the surface of the conference table 204.

In some embodiments, the portion of each USB cable 206A-F, the power cable 208, and/or the video cable 210 that is not integrated into (or installed underneath) the conference table 204 may be removably attached to and from the integrated (or underneath) portion of such cable at a location at or near where the cable presents through or away from the conference table 204. Removing the portion of each such cable that is not integrated into (or underneath) the conference table 204 when that cable is not being used may help reduce unnecessary clutter. This optional removability may be accomplished via, e.g., a USB socket on the end of the integrated portion of each USB cable 206A-F at or near the location it presents through or away from the conference table 204 and a USB plug on the end of the unintegrated portion of each USB cable 206A-F that attaches to the socket of the integrated portion of the USB cable 206A-F. Similar strategies can be taken using sockets and plugs compatible with the other cables that may be used by the conferencing device 202 (e.g., the video cable 210, the power cable 208, any audio cables, any networking cables, etc.).

The sockets and/or plugs corresponding to one or more USB cables 206A-F may each respectively be USB-C type sockets and/or plugs, or alternatively they may each respectively be sockets/plugs of another USB type. The USB type of the socket of the integrated portion of a USB cable 206A-F does not need to match the USB type of the port of the USB hub of a conferencing device 202 to which the other end of the integrated portion of the USB cable 206A-F is attached. Further, the unintegrated portion of the USB cable 206A-F may have differently typed USB plugs/connectors on each end in order to permit compatibility between, e.g., a socket of an integrated portion of the USB cable 206A-F that is of one type and an interface on an external host device that is of another USB type.

The USB cables 206A-D are illustrated coupled to a corresponding external host device/portable electronic devices 212A-D associated with a meeting participant 214A-D. The external host devices 212A-D may be embodied as a laptop, smartphone, tablet, or another type of device that includes a USB interface for communicating with the USB cables 206A-F. A USB interface on an external host device may be a USB-C type interface, or alternatively may be an interface of another USB type. In the embodiment of FIG. 2 , the USB cables 206E-F are not shown connected to an external host device. As previously stated, each USB cable 206A-F has a corresponding connector, such as connectors 207E-F, to enable coupling with a USB interface.

The power cable 208 may be attached to a wall outlet 218 or other source of power in order to provide power to the power supply of the conferencing device 202. Power received at the power supply in this way may then be provided to the USB hub of the conferencing device 202. Some of this power may then be transported from the USB hub to one or more of the external host devices 212A-D via the USB cables 206A-D.

The video cable 210 may be attached to a presentation device 220 and may transport video data from a video out port of the conferencing device 202 to the presentation device 220, which may be placed in a manner that each participant 214A-D may comfortably and easily view the video data on the presentation device 220. Optionally, the video cable 210 may also transport audio data associated with the video data, which may also be reproduced (in some cases) by the presentation device 220 (e.g., should the presentation device 220 have built-in speakers). While the presentation device 220 has been illustrated in FIG. 2 (and other figures throughout) as a device containing a display panel, other types of presentation devices are also contemplated (e.g., a projector type presentation device).

Alternatively, the conferencing device 202 may transport such video and/or audio data to the presentation device 220 via another cable, such as a USB cable attached to a USB port of a USB hub of the conferencing device 202, or via a network cable attached to a physical network interface of the conferencing device 202. As a further alternative, the conferencing device 202 may transport such video and/or audio data to the presentation device 220 wirelessly via, e.g., a wireless network interface or a Bluetooth interface of the conferencing device 202.

The conferencing device 202 may be connected to a speaker 222 via a Bluetooth connection. This may allow the speaker 222 to reproduce audio associated with the presentation (e.g., the voice of a presenter or other participant in the video conference). This may be especially useful in the case where a presenter or other participant who is currently speaking is at a location other than the location of the conferencing device 202, and where the audio associated with the presentation is arriving to the conferencing device 202 via a network interface (as discussed in relation to FIG. 1 ). In alternative embodiments, the speaker 222 may be connected to the conferencing device 202 via a cable attached to an audio out port of the conferencing device 202. In these cases, the audio out cable may be integrated into (or installed under) the conference table 204 similarly to other cables already herein described.

The conferencing device 202 may be in electrical communication with a microphone 224 via a Bluetooth connection. This may allow the microphone 224 to capture audio associated with the presentation (e.g., the voice of a presenter or other participant in the video conference). This may be especially useful where a presenter or other participant who is currently speaking should be heard at a location other than the location of the conferencing device 202, and where the audio associated with the presentation is sent to a remote conferencing device via a network interface of the conferencing device 202 (as discussed in relation to FIG. 1 ). In alternative embodiments, the microphone 224 may be in electrical communication with the conferencing device 202 via a cable attached to an audio in port of the conferencing device 202. In these cases, the audio in cable may be integrated into (or installed under) the conference table 204 similarly to other cables already herein described.

Software may be installed on each of the external host devices 212A-D to enable the devices to send video data and/or control signals to the conferencing device 202 when connected. The function of this software will now be described in terms of one external host device 212A as it is operated by one of the participants 214A-D. However, it should be understood that each of the external host devices 212A-D as operated by the participants 214A-D (or another connected external host device operated by another participant) may have the same features.

The participant 214A may use the software on the external host device 212A to control the sending of this video data and/or control signals to the conferencing device 202. Specifically, it may be that the participant 214A may use the software on the external host device 212A to instruct the external host device 212A to send a control signal to the conferencing device 202 to instruct the conferencing device 202 to begin receiving video data from the external host device 212A. In response to the receipt of this control signal, the conferencing device 202 may enter a state where it is ready to receive video data from the external host device 212A. Once this control signal has been sent, the external host device 212A may begin sending video data to the conferencing device 202. The video data may be a representation or mirror of the content that is on the screen of the external host device 212A. This video data may be received at the USB hub of the conferencing device 202 and from there transported to the processor of the conferencing device 202. The processor of the conferencing device 202 may then place that video data at a video data output of the conferencing device 202 for transport to the presentation device 220.

That the video data may be a representation or mirror of the content that is on the screen of the external host device 212A makes presentation using the presentation device 220 a simple matter for the participant 214A, who merely must use the external host device 212A in a regular fashion to present their content on the screen of the external host device 212A in order to have it appear on the presentation device 220.

The video data from the external host device 212A may continue to be transported to the presentation device 220 for display until such a time as the participant 214A uses the software on the external host device 212A to instruct the external host device 212A to stop sending video data and/or to send the conferencing device 202 a control signal instructing it to stop using video data from the external host device 212A. Alternatively, the video data from the external host device 212A may continue to be transported to the presentation device 220 for display until such a time as one of the participants 214B-D uses the interface on one of the external host devices 212B-D to send the conferencing device 202 a control signal instructing it to use video data from their respective external host device 212B-D instead of the video data received from the external host device 212A.

It is contemplated that, at times, more than one of the external host devices 212A-D (or another external host device) may provide video data to the conferencing device 202 for display to the presentation device 220. The processor of the conferencing device 202 may be configured to combine the video data from two or more external host devices into combined video data before placing the combined video data at a video out module for transmission to the presentation device 220. The conferencing device 202 may adapt in real time by dividing the screen of the presentation device 220 to provide screen space to each (or at least a multiplicity) of the external host devices that is connected to the conferencing device 202 and that has sent a control signal to the conferencing device 202 to instruct the conferencing device 202 to receive video data from that respective external host device for display on the presentation device 220. The conferencing device 202 may further adapt by consolidating screen space on the presentation device 220 for use by any remaining active video data connections when one or more external host devices cease providing video data to the conferencing device 202 for transmission to the presentation device 220.

As will be discussed in further detail below, it is contemplated that in some embodiments, more than one presentation device may be attached to the one or more video out ports or video out wireless interface of the conferencing device 202. In these cases, the video data presentation, screen splitting, and screen consolidation methods discussed herein may be spread across all of the connected presentation devices by the conferencing device 202.

In embodiments where one or more remote conferencing devices are being used (in addition to the conferencing device 202) to facilitate a presentation to participants at two or more locations, all video and control signals discussed herein may be passed between the conferencing device 202 and the one or more remote conferencing devices via the network interface of the conferencing device 202. Each of the conferencing device 202 and the one or remote more conferencing devices may respond to any control signal or video data from the external host devices 212A-D (or any external host device connected to a remote conferencing device) in the manner described above. Further, any audio captured by a microphone of any conferencing device may be transported and reproduced on a speaker of any conferencing device that is remote to the conferencing device where the audio was captured.

The embodiment of FIG. 2 has discussed a system that provides a USB cable (e.g., the USB cable 206A-F) to each of one or more devices 212A-D for the participants 214A-D using USB cables integrated into (or installed underneath) the conference table 204. It is contemplated that similar cable provisioning to one or more participants could occur using different types of cables other than USB cables, e.g., power cables, audio cables, network cables, and the like. It is contemplated that these cables may be attached (either directly or indirectly) to an appropriate device (e.g., the conferencing device 202, the presentation device 220, the outlet 218, a network switch, etc.) to provide the power and/or data delivery that is normally associated with the given type of cable. The provisioning of one or more of these different types of cables in this way could be in addition to, or separately from, the provisioning of the USB cable to one or more participants as herein described.

FIG. 3 illustrates a system 300 of directly connected conferencing devices in a conference room setting, according to an embodiment. The system 300 includes a first conferencing device 302 and a second conferencing device 304 connected and in electrical communication with each other via a cable 306. The conferencing devices 302, 304 may be embodied similarly to that of FIG. 1 . USB cables 310A-F are in electrical communication with a USB hub of the first conferencing device 302. The USB cables 310A-F are in electrical communication at the other end, through use of suitable connectors, to external host devices 312A-F. Each external host device 312A-F has a corresponding participant 314A-F. USB cables 316A-F are in electrical communication with a USB hub of the second conferencing device 304. The USB cables 316A-C are in electrical communication at the other end, through use of suitable connectors, to external host devices 318A-C. The external host devices 318A-C each have a corresponding participant 320A-C. The USB cables 316D-F are not in electrical communication with external host devices and remain unused.

The first conferencing device 302 draws power from a wall outlet 321 via a power cable 322. The first conferencing device 302 is also in electrical communication with a presentation device 324 via a video cable 326. Similarly to the embodiment of FIG. 2 , dotted lines represent elements (or portions of elements) that are integrated into (or installed underneath) a conference table 328. As described in relation to FIG. 2 , the portion of each USB cable 310A-F, 316A-F (or any other cable, such as the power cable 322 and/or the video cable 326) that is not integrated into (or installed underneath) the conference table 328 may be removably attached to the integrated (or underneath) portion of such cable at a location at or near where the cable presents through or away from the conference table 328.

The connection of the first conferencing device 302 to the second conferencing device 304 via the cable 306 may be between an expansion port on each of the conferencing devices 302, 304. Alternatively, the connection may be made between ports on the USB hub on each of the conferencing devices 302, 304 or between an expansion port on one of the conferencing devices 302, 304 and a port on the USB hub on the other of the conferencing devices 302, 304. However made, the connection via the cable 306 may allow the conferencing devices 302, 304 to act in concert as a single logical conferencing device that can handle more external host devices than may be possible using only a single physical conferencing device.

As shown in FIG. 3 , the presentation device 324 may be physically connected to the first conferencing device 302. The first conferencing device 302 may be able to display video data from one or more of the communicating external host devices 312A-F to the presentation device 324 in the manner described above in relation to FIG. 2 . The second conferencing device 304 may be capable of receiving control signals and/or video data from any of the external host devices 318A-C that are in electrical communication with the second conferencing device 304. The second conferencing device 304 may further transport control signals and/or video data from the second conferencing device 304 to the first conferencing device 302 via the cable 306. The first conferencing device 302 may treat any control signals and/or video data arriving from the second conferencing device 304 on the cable 306 just as it would treat any control signals and/or video data arriving on one of the USB cables 310A-F from a respective external host device 312A-F. In this manner, the external host devices 318A-C can instruct the first conferencing device 302 to begin receiving video data from an external host device 318A-C, and subsequently have that received video data placed at a video out port of the first conferencing device 302 for transport to the presentation device 324 just as if such an external host device 318A-C were in direct electrical communication with the first conferencing device 302.

In some embodiments, the power supply of the first conferencing device 302 may send power over the cable 306 (or another cable like it) to power the second conferencing device 304 and also to power the USB hub of the second conferencing device 304 to in turn provide power to the external host devices 318A-C. In other embodiments (not shown), a power supply of the second conferencing device 304 is connected to an external power source to provide power to the second conferencing device 304 and to act as a power source from which the USB hub of the second conferencing device 304 can draw to provide power to the external host devices 318A-C.

In embodiments where one or more remote conferencing devices are used (in addition to the first conferencing device 302 and the second conferencing device 304) to facilitate a presentation to participants at two or more locations, all video data and/or control signals discussed herein may be passed between the first conferencing device 302 and/or the second conferencing device 304 and the one or more remote conferencing devices via the network interface(s) of the conferencing device(s) 302, 304. Each of the conferencing devices 302, 304 and the one or more remote conferencing devices may respond to any control signal and/or video data from the external host devices 312A-D or 318A-C (or any external host device connected to a remote conferencing device) in the manner described above. Further, any audio captured by a microphone attached to any conferencing device may be transported to and reproduced on a speaker attached to any conferencing device that is remote to the conferencing device where the audio was captured. Similarly to the first conferencing device 302 and the second conferencing device 304, any remote conferencing device may be acting in concert with another remote conferencing device via a physical connection to act as a single logical conferencing device.

Similarly to embodiments described in relation to FIG. 2 , it is contemplated that in addition to (or separately from) providing USB cables (e.g., the USB cables 310A-F, 316A-F) to one or more participants (e.g., the participants 314A-F, 320A-C) in the manner described, cable provisioning to one or more devices could also occur with different types of cables, e.g., power cables, audio cables, network cables, and the like.
